To tell you the truth, I aint looked at my installation instructions for mine, I just give it to the auto-electrician who installing it and let him do his stuff. I was kind of under the impression that the RS didnt have a speed sensor that could be used, hence the auto function was defunct, and the guy who installed it said something along the lines of it only really being used on jap cars.

Anyway, now I know it's possible, I shall go back down armed with my AK-47 and DEMAND that he fixes his appauling mistake!
